Description

Title: Exceptional Holography

Abstract: Under certain circumstances, quantum gravity shows holographic behaviour: its degrees of freedom are captured by a quantum field theory defined in some boundary region. In cases for which one has good control over the semiclassical gravitational description, the challenge is to determine what the dual field theory is. The field theory can be partially characterised by its operator spectrum, and this can be often computed from the gravity side. In this talk, I will report on recent progress in this direction within a particular realisation of the holographic principle in terms of string theory and the anti-de Sitter/conformal field theory correspondence. I will also describe how string dualities of exceptional type play a central role in this approach.

Bio: Oscar Varela is an Associate Professor of Physics at Utah State University and a research fellow at IFT-Madrid. He received his PhD from Valencia University, Spain, and completed postdoctoral research at Imperial College, Max Planck, Utrecht and Harvard. His work lies at the interface of quantum gravity and high energy physics, exploring holographic aspects of the former using string and quantum fild theory.
